Most recent kernel where this bug did *NOT* occur: 2.6.20 Distribution: Gentoo Problem Description: when thermal zone is enabled in kernel and module is loaded when system is overloaded (glibc compilation or other long compilation process) system hangs Steps to reproduce: compile glibc on thremal zone enabled kernel
*** Bug 8518 has been marked as a duplicate of this bug. ***
What model machine is this? Did this work properly in all releasese tested before 2.6.21? Please attach the output from acpidump Please attach the complete output from dmesg -s64000 Please paste the contents of /proc/acpi/thermal_zone/*/* here Please monitor the /proc/acpi/thermal_zone/*/temperature and /proc/acpi/fan/*/* and report what you see before the system hangs. I assume it is rising and the hang occurs at some trip-point or perhaps a thermal failure. Is the fan spinning at full speed when the failure occurs?

Try to _enable_ polling: echo 2 > /proc/acpi/thermal_zone/THRM/polling_frequency If that does not help, please attach disassembled dsdt.
